A ski-inspired design to keep you dry and warm, the Alpen Component Jacket is a marvel of wintertime protection. The seam-taped, two-layer construction uses Marmot's waterproof/breathable MemBrain fabric. A removable Thermal R lining adds insulating warmth for rougher conditions, or can be used as a lightweight jacket on its own. A powder skirt, venting PitZips and zip-off storm hood with a laminated brim add on-the-mountain versatility.
